Well, I frequent the bars around the Presidio, the closed beeing the 'Final Final' directly at Lombard gate. Haven't noticed anything especially strange around there apart from the unusually high percentage of false blondes in the marina district.
It is actually a pretty nice area down there. People are friendly, educated, the local Safeway was for time the best place to meet women. There are actually many more women than guys living there. Here we go, this is the real reason those hopelessly geeky artists and programmers want to move from San Rafael to San Francisco city...
The whole point of this patent is that it actually does not represent an alpha mask, but each pixel in the mask represents a blending value seperatly for each channel. Usually it is used in the form A*I + B*(1-I), where A and B are the images to be blended and I is the blending value.
This technique is used to get those fancy transition effects in Final Cut and iMovie. It allows to implement a wide range of effects like wipes, fades, color effects etc. It can represent most effects which do not require pixel displacement. The big advantage is that you actually precompute the effects and then simply feed the resulting animated blending mask and the two video sources to some highly optimized code/hardware without the need of specific code for each effect.
This looks more like a thing which is used in Final Cut Pro and iMovie. A bunch of the effects are rendered this way. The mask is simply a prerendered bitmap animation with 8bit depth in this case. Very powerful stuff since it allows to create a wide range of effects, yet very easy to optimize since its very generic.
